This invention relates to improvements in hose couplings *which are usedin connection with garden hose and particularly lire hose.

An object of the invention resides in providing a hose coupling in whichthe parte are adapted ier assembly and detachment Without the use or"-wrenches, screw drivers.-

iaminers or the'lilte, and in which the parte may be easily assembledand disassembled 'for use by hand.

it further 1object of the invention resides in providing a'hose couplingin which a female member is formed with a chamber adapted to receive amale assembly including; a `lair el relatively movable elements mountingan enpansible packing' and locking,- member so that the insertion ot'the male'assembly inte the chamber of the female member is ob tained inone relation of the elements, and one element then moves relative to theother so as to expand the enpansible member carried thereby :for lockingcooperation `with the female member to lock said ina'le assembly incoupled relation with the female member with suitably means for normallyoperating' the elements to permit insert-ion and removal olf the maleassembly from the female member, and other means to {Jerlnit the lockinget the parts in zr'semblet relation, packinger expansible means inexpanded relation..

The invention conipi'ehends nnnierous other objects residing in thedetails of construction and arrangement of the parts which ere moreparticularly pointed outin the following; description and claim,directed to a preferred Vform ot the invention, itbeiner nn derstoodghowever, that various changes in the size, shape and arrangement of theparts may be made Without departing from the spirit end scope oftheinvention as herein forth.

Fig. 2 is a vertical longitudinal section thr'n the coupling shown inFig. i.

l indieates the Female member ot' the eonplinfr, While d indicates themele `assembly The female member is formed'with a; ro duced threadedextension 3 at one end to receive the end of e flexible hoseA or4 thelike indicated at 4 which `is retained on the threaded end threugh thecooperation of the threads of the reduced extension. 3 internally ot thehose, andthe band spirals arranged externally thereon. The major portionof the female member is provided with :1n enlarged internal cylindricalchamber 6, which at the free end thereot' is provided with the inwardlyextending flange 7, restricting the opening into the chamber asillustrated in Fig. 2.

'.lhe male member includes a hose engaging member S formed with e.central annular l'ange 9 having the' opposite ends of vthe with thecollar and hose engaging member.'

The free end of the flanged nipple 13 is externally threaded 1. forthreadedly receiving the internallyv threaded collar le, the oppositeend of Which threadedly mounts tapered packing carrying element. l5,particularly illnstrated'in Fig. Q. This element 15, has the free endthereof flared outwardly as indicated at le and formed with an annularoutvvar ly projecting ange 17 on the end thereof of a diameter slightlyless than the vinternal diameter of the flange 7 of the female member sothat the element may be freely inserted into the chamber 6 into thefemale member as shown in Fig. 2.

A sleeve element 18 is slidebly mounted on the collar lll and isprovided with an internal flange adjacent one end as indicated at 19with which engages the expansible coiled spring 20 having abutments aainst one end of the collar 14 as shown in ig. 2, so that the sleevemember 18 is normally operated to slide on the collar 14 toward the freeend of the element l5 as shown in Fig. Q. The sleeve member 1S is heldagainst rotation on the collar 14: through the pair of pins 21 providedon the collar 14 engagin in the bayonet slots 2Q Vformed in one en ofthe sleeve t8, the opposite end of the sleeve 18 beingformed with anannular ex ternal flange 23 spaced from the end portion as shewnin Fig-2 fiumi lahm-Lilie sp1-ing 20 mible resilient packing' and locking ibm'9A- whicli ia ol' G i/lindi'iwil fumi, is il. wel' lli@ aleman? )l5 isshown in liigg.
